• The reality is, there is no “better” or “worse” in the automated vs. manual debate, there’s just “different.” Each approach has its own advantages and disadvantages. Manual testing is performed by a human sitting in front of a
• computer carefully going through application via SQL and log analysis, trying various usage and input combinations, comparing the results to the expected behavior and recording the results. Automated testing is often used
• after the initial software has been developed. Lengthy tests that are often avoided during manual testing can be run unattended. They can even be run
• on multiple computers with different configurations.

hjasgs sdhhsda  asjkdhads manual and automated testing have their roles, especially if the software you’re developing is too large and too complex to rely just on the manual approach.

In the section above we looked at what share renewable technologies collectively accounted for in the energy mix.

In the charts shown here we look at the breakdown of renewable technologies by their individual components – hydropower, solar, wind, and others.

The first chart shows this as a stacked area chart, which allows us to more readily see the breakdown of the renewable mix, and relative contribution of each. The second chart is shown as a line chart, allowing us to see more clearly how each source is changing over time.

Globally we see that hydropower is by far the largest modern renewable source [since traditional biomass is not included here]. But we also see wind and solar power are both growing rapidly.
